1G Diesel Noise (video) Rod Bearing? Or something else.

[a91eagletalon]

Ok so I am debating on whether to pull the motor or not I am not convinced its the rod bearing but it very well could be . it clatters like a diesel engine at idle and up to like 1500 rpm then it goes away completely then when it idles back down its back.

Now when it is cold right after I start it. it doesn't make that noise till after a minute of idling then it starts.

Also after I drive it for a while and it is good and warmed up it is a lot more faint you can still here it but probably about half as loud.

I attached two video's the first one is probably 5 min after starting the car so it’s about halfway warmed up. there is a lot of engine noise so it is a bit hard to hear what I am talking about so I attached a second video with the hood down from the outside of the car you can hear it better.

Most of noise seams like it is coming fro the backside of the block. the balance shaft is removed.

Oil press at idle cold is 80psi
Oil press at idle hot is 20psi

Oil presser driving cold is 90-100psi
oil presser driving hot is 50 or so

so my question is what's causing that noise and should I be driving it or not.

thanks for the help guys.

I could be wrong but it sounds like maybe a rod bearing. My 06 hummer did the same before the engine blew up. If someone else knows for sure what this is please let me know as well im interested to find out the exact cause of this problem is

It does sound kind of bottom-endy. You might try listening around with an automotive stethoscope. See if you can isolate where the sound is coming from.

Good luck

Ya ill have to do some checking it makes me a bit mad it only has owww 2500 or so miles on the bearings/rebuild dose my oil press seam to be ok

it should to me like I should just pull the motor and check the bearings and what not and hope nothing needs ground.
